What Affects the Lifespan of Artificial Grass?

July 31, 2025 Sophia Facey

Thinking about putting in artificial grass and want to know how long it will stay good? The life span of fake grass can be very long—often over 15 years—but that's if you treat it well. Many things, from how much sun and rain it gets to how many people walk on it, the way it's put in, and how you keep it up, can make your lawn stay green or wear out fast. Whether you want to pretty up a family yard, a spot for pets to play, or a great-looking front lawn, it helps to know what makes your fake grass last longer. In this blog, we're sharing all the details on what impacts the life of fake grass—and how you can help it look great for a long time. Let's start!

1. UV Stability and Material Quality:

Not all fake grass is the same. The main parts—often made of polyethylene, polypropylene, or nylon—are not alike in soft feel, strength, and UV fight. Cheap fake grass may not have enough UV protection, making it fade and get brittle far too soon under the UK sun.

• UV Stabilisation: Seek grass with UV stabilisers in the threads. These mix-ins push back bad sun beams, making the color stay bright for more time.

• Thickness of Wear Layer: A thick wear layer (0.5 mm or more) can deal with a lot of use. Yet, very thin ones might show worn-out spots soon.

Pro-Tip: Ask your supplier for UV fade test results—some brands give out ΔE values that show color shifts in usual settings.

2. Density and Pile Height:

"Pile" means how tall the grass blades are; density is about how close they are to each other. Both change how long they last:

• High Pile (30–40 mm): Feels soft but gets flat when used a lot—best for places where not many walk.

• Medium Pile (25–30 mm): Mixes being soft and tough for home grass.

• Low Pile (15–25 mm): Liked on sports fields and busy places since it stays up well.

Density (stitches per square metre) is key. Dense weaves feel better under your feet.

Pro-Tip: For gardens used for more than one thing, pick a medium pile (30 mm) with high density (12,000+ stitches/m²). It's perfect for both comfort and lasting use.

3. Infill Amount & Selection:

Infill keeps blades up, adds weight, and softens blows. Yet, not all infills last the same:

• Silica Sand: It's cheap and common but can pack tight and hold heat.

• Crumb Rubber: It's soft and good for shocks, but may give off gas and make the top dark.

• TPE/Cork Blends: Cost more but are good for the earth and light—stay cool and don’t pack tightly.

The right infill depth (4–8 kg/m²) stops blades from bending and lowers stress on the back.

Pro-Tip: In places with strong sun, match light-colored cork infill with your grass—it lessens heat soak and feels bouncy when you step on it.

4. Essentials of Sub-Base and Drainage:

Under the turf, a good sub-base keeps things stable and deals with water:

• Crushed Stone Base: A 50–75 mm layer of MOT Type 1 packed stone stops sinking and helps water flow.

• Geotextile Barrier: Blocks weeds and keeps soil apart from stones for lasting quality.

• Falls & Slope: A small slope (1–2%) makes sure rain does not gather and harm glues and bases.

Bad sub-base work can cause dips, water build-up, and early base wear.

Pro-Tip: Use a plate compactor in three 25mm lifts; missing layers can mean uneven settling and weak spots.

5. Edge Fixing and Installation Quality:

The good stuff goes bad with the bad setup:

• Seam Accuracy: Joints need to be stuck with sun-safe glue and pressed down with heavy stuff for 24 hrs. Space between them can lead to stuff inside getting out and the sides lifting up.

• Edge Anchoring: Use strong U-pins or edge boards to keep the turf stretched tight; if not, the edges might wave in the wind and catch on things.

• Expanding Gaps: Put a small gap (5–10 mm) near walls and solid builds for when it gets hot, and the turf swells—without this gap, it will bow up.

Pro-Tip: Always get trained people to do the job—DIY jobs often can't take jumping and weather as pros can.

6. Sun Exposure & Climate:

UK weather changes a lot, but fake grass reacts to:

• Sunlight Intensity: Sun hits southern spots harder than shaded north sides, speeding up UV damage.

• Frost & Rain: Strong drainage helps rain clean junk off, but still water freezes and breaks the base.

• Seasonal Maintenance: Clean it up well after leaves fall in autumn and after winter messes. This keeps mould and wet spots away.

Pro-Tip: In places full of sun, move your chairs and tables around and spray the grass every week in hot times to keep the ground cool.

7. Usage Patterns & Foot Traffic:

A calm yard gets less use than a kid's play spot or a spot for dogs:

• High-Traffic Areas: Lay down path support tape under joins or place stones meant for walking.

• Pet Areas: Dogs that dig or sprint can tear up grass quickly—choose sport-level, 20 mm depth with thick support.

• Movement of Furniture: Don't drag heavy things—use slide pads or short-term plywood when moving to stop wear.

Pro-Tip: Draw where people walk the most when setting up. Light fill can fix worn paths more quickly than hard cleaning.

8. Maintenance Procedures & Errors to Steer Clear of:

Good care makes things last; bad moves make them break:

• Brush Regularly: Each month, use a hard brush to make space in the fill, raise the blades, and stop them from clumping together.

• Remove Debris: Every week, use a leaf blower to stop dirt and rotting bits from getting stuck in the pile.

• Spot Clean: Clean up spills fast; don’t use bleach or harsh cleaners that harm the fibres and their bases.

• Don't Use Steam Cleaning: Hot steam and wetness can break down the glue and make the backing weak.

Pro-Tip: Get a power broom—it pays off to rent it for top-notch fluff and to spread the infill well, twice a year.

Factor	Description	Impact on Artificial Grass Lifespan
Material Quality & UV Stability	Artificial grass made from polyethene, polypropylene, or nylon with UV stabilisers.	High-quality materials resist fading, cracking, and brittleness caused by sunlight.
Density & Pile Height	Refers to the blade height and the degree to which the fibres are stitched together.	Higher density and the right pile height improve durability and maintain appearance.
Infill Type & Amount	Materials such as silica sand, crumb rubber, or cork are used between grass fibres.	Proper infill supports blades, improves cushioning, and prevents early wear.
Sub-Base & Drainage	A strong base layer made of compacted stone with drainage support.	Prevents water accumulation, sinking, and uneven surfaces.
Installation Quality	Correct seam joining, edge fixing, and proper spacing during installation.	Professional installation prevents lifting edges and premature damage.
Sun Exposure & Climate	Continuous exposure to strong sunlight, frost, and heavy rain.	Extreme weather can affect colour, flexibility, and structural stability.
Foot Traffic & Usage	Areas with frequent walking, pets, or play activities.	Heavy use may flatten fibres or cause faster wear in specific spots.
Maintenance Practices	Regular brushing, debris removal, and proper cleaning methods.	Consistent maintenance helps the turf maintain its shape and extend its lifespan.
